IFIP-UNU ADVANCED COURSE ON NETWORKING AND SECURITYModule II-Wireless CommunicationsSection 5 • Access Points
Overview • This module covers basic access point (AP) installation and configuration. An access point acts as a communication hub for wireless network users. An access point can link wired and wireless networks together. The goal of this module is to get the AP configured and communicating with clients and other APs. It is important to keep the configuration simple until connectivity is achieved. Later in this module, more detailed port configurations and services will be covered
Learning Objectives • Demonstrate the proper AP setup and connection • Properly connect to the AP • Demonstrate Configuration proficiency via IOS GUI • Demonstrate Configuration proficiency via IOS CLI

Assigning IP Address Using IOS CLI • Connect a console cable between PC and AP. (Use “typical” serial settings.) • Enter enabled mode: enable (Default password: Cisco) • Enter global configuration mode: config t • Enter interface configuration mode: interface bvi1 • Assign IP address: ip address <address> <mask> • End and save configuration: copy run start
Proxy Mobile IP Devices • A visiting client device that can associate to an AP. It does not need any special proxy Mobile IP software. • An AP with proxy Mobile IP enabled. • An authoritative AP on your network supporting proxy Mobile IP. The authoritative AP uses a subnet map to keep track of the home agent information for all visiting client devices. • A home agent. The home agent is a router on the visiting client’s home network that serves as the anchor point for communication with the AP and the visiting client. The home agent tunnels packets from a correspondent node on the Internet to the visiting client device. • A foreign agent. The foreign agent is a router on your network that serves as the point of attachment for the visiting client device when it is on your network, delivering packets from the home agent to the visiting client
